The paper further elaborates on a passive output that was constructed in [3] with the purpose of providing an energybalance (EB) interpretation for basic interconnection and damping assignment (BIDA [6, 7]). Such output has its roots in power shaping [4], an alternative method to stabilize nonlinear RLC circuits subjected to the dissipation obstacle [6]. It has been recently shown in [5] that t...

Ultrafast laser processing applications need fast approaches to assess the nonlinear propagation of the laser beam in order to predict the optimal range of processing parameters in a wide variety of cases. We develop here a method based on the simple monitoring of the nonlinear beam shaping against numerical prediction. The numerical code solves the nonlinear Schrödinger equation with nonlinear...

This paper proposes a simpler solution to the stabilization problem of a special class of nonlinear underactuated mechanical systems which includes widely studied benchmark systems like Inertia Wheel Pendulum, TORA and Acrobot. Complex internal dynamics and lack of exact feedback linearizibility of these systems makes design of control law a challenging task. Stabilization of these systems has ...

A methodology is proposed for optimal shaping of permanent magnets with non-conventional and complex geometries, used in synchronous motors. The algorithm includes artificial neural network-based surrogate model and multi-objective search based optimization method that will lead to Pareto front solutions. An interior permanent magnet topology with crescent-shaped magnets is also introduced as t...

Sensor networks provide sensing capability in a wide range of application domains such as healthcare, home, military, commercial and so on. Typically, energy is much more limited in sensor networks than in other wireless networks. This is due to the intrinsic nature of sensing devices and the difficulty in recharging their batteries. The nodes in the network usually dissipate energy by transmit...

The technique of input shaping has recently been successfully applied to the problem of maneuvering exible structures without excessive residual vibration. In the method of input shaping, positive impulses are often desired because they can be used with any arbitrary (un-shaped) commands and do not cause actuator saturation (if these original unshaped commands do not cause ac-tuator saturation)...
